We currently have the ability to upload a file to add to the DNC list but we do not have the ability to upload a file to take off the DNC list. We have hundreds of records every day that we need to add and hundreds that we need to remove but currently the only way to remove them is manually one at a time.
I was just at the DNC.com TCPA Summit last week and there are lawsuits in the works right now for this very reason. They are specifically looking at whether or not the clients DNC match the vendors DNC. So not only would this be more helpful and efficient but it may also be a liability issue.
